Convert the common bridge code and the two rockchip & stm drivers
which currently use it to the regmap API in anticipation for further
changes to make it more generic and add older DSI host controller
support as found on i.mx6 based devices.

The regmap becomes an internal state of the bridge. No functional
changes other than requiring the platform drivers to use the
pre-configured regmap supplied by the bridge after its probe() call
instead of ioremp'ing the registers themselves.

In subsequent commits the bridge will become able to detect the
DSI host core version and init the regmap with different register
layouts. The platform drivers will continue to use the regmap without
modifications or worrying about the specific layout in use (in other
words the layout is abstracted away via the regmap).

I should have been clearer earlier - I didn't quite review the patch.
Is is now though.

Admittedly a couple of nitpicks (DRIVER_NAME, zero initialize of val)
could have been left out.
It's not a big deal, there's no need to polish those.
